Simplify build system.
The logit tool is, as of v4.0, installed into /libexec/finit/logit and
thus not part of the system $PATH. If a sysadmin or distro wants to
remove it from the system it's entirely possible since Finit always
checks for logit availability before attempting to use it.

Most major init systems have a way to start a rescue shell. This is
usally started when the string `rescue` is read from the kernel's
command line.
The traditional Finit way of handling this has been to skip certain
phases of the standard boot, skip /etc/finit.conf et al, and go for a
/lib/finit/rescue.conf instead. This pratice has been imroved over
the last few commits with a sulogin. However, there was no way to
resume boot, like most other init systems offer.
This patch implements a very simple rescue mode, utilizing the new
sulogin, replacing the old (and experimental) emergency shell. If
Ctrl-D is pressed at the maintenance login prompt the boot is now
resumed. The same goes for exit/Ctrl-D from the maintenace shell.
The preferred sulogin is the bundled /libexec/finit/sulogin, but
if that isn't installed, the first one in $PATH is used. If no
sulogin at all is found, Finit proceeds as before this patch, to
skip certains steps and go for a /lib/finit/rescue.conf. Hence,
al steps can be controlled by an administrator.

This changes the default to redirect output from run/task/services to
/dev/null. Use --disable-redirect to get the old pre v4.0 behavior.

This patch changes the configure option to enable the built-in watchdog
from --enable-watchdog to --with-watchdog[=DEV]. This is the convention
for features that take arguments.
Also, improve log messages to aid debugging when finit-watchdogd does
not start properly. This means flushing logs to syslogd with closelog()

- Refactor screen_init()
- use native impl. of TTY probing from pimd project
- check if TIOCWINSZ works
- check if we're running in watch(1), for initctl
- check if ANSI goto(999,999) escape seq. works (invasive)
- fallback to 80x24
- Drop screen_exit()
- Rename screen_init() to get_width(), for now, matching pimd
- Relocate call in main() to banner(), first fn to write to TTY

Both Debian and Builroot based systems use /etc/default and
Alpine Linux use /etc/conf.d, so let's just put both in by
default. If the directories exist we monitor them.
The --with-syconfig configure option is now disabled by default.

This patch reverts back to the progress/status behavior of Finit < v3.0
because this is what most users expect, including the maintainer. The
resulting code and configure script is a lot simpler to understand and
maintain:
- No more --enable-progress or --enable-progress-classic configure
flags. Instead a progress_style variable in helpers.c that can
be changed at compile time for those that really need it.
- No more 'splash' kernel commnand line option. This turned out to
be *very* confusing to many users who believed it was some sort of
graphical splash screen à la Plymouth.
Also, when Finit debug is enabled we now have a global 'debug' flag
which now alo controls if klogctl() should be called to prevent the
kernel logs to the console or not.

In the v4 bump we removed tar.xz archives in favor of bringing back
tar.gz. This was a bit premature and could easily cause unnecessary

The SysV API compatibility layer gives too little value to be worth
the effort of maintaining it. Users are encouraged to use the

This patch removes the built-in inetd support from Finit. We recommend
using an external inetd instead, e.g. xinetd.
If you liked the feature set our inetd provided; filtering per interface
and port redirection, then please let us know or use the code in this
patch (MIT licensed) to recreate it. We are open to reintroducing it,
but then as a stand-alone daemon like the bundled watchdogd and getty.
So long for now, old friend.

Planned changes will directly change the behavior of conditions, and
instead of having to implement compatibility wrappers and further
complicate the code, we've taken the decision to go for v4 directly.
This allows us to also rip out the complex inetd support.
Other changes in this commit:
- Revert back to .tar.gz distribution archives, by popular demand
- Add .sha256 checksum for .tar.gz archive

As documented in the kernel docs and systemd[1], the default system
console is the first listed in /sys/class/tty/console/active, which
is the reverse order of console= given on the kernel cmdline.
Some distros don't have console= on their default command line in
their bootloader, e.g. Alpine Linux, some multiple, e.g Buildroot.
Instead of relying on the value given at configure time we probe
sysfs and open all (at most three) consoles listed. This way we
at least get the default console for our progress output.
- drop old --with-console from configure script
- drop /proc/cmdline fishing in favor of sysfs
- replace CONSOLE from configure with new console()

The logit tool is not just used by scripts and such, when logger is
absent. It is also used by Finit internally to redirect logging of
services to syslog and/or log file, with log rotation.
This patch reverts the default to enabled. Someone explicitly has
to disable logit now to get less functionality.

`--disable-logit` at configure time means redirecting stdout from a
service to a file is completely disabled. Fallback to `logger` can
not be guaranteed to provide log file rotation, so all logs will be
sent to syslog instead. In case logger is also missing, a simple
redirect using fork() + syslog() is used as fallback.

Since sysklogd now ships an excellent enhanced logger tool there is no
need for Finit to provide its own tool for the same purpose by default.
